Description of the drawings
Fig. 1 is the structural schematic diagram of the front end crash energy absorption equipment for the rail vehicle that the utility model embodiment provides.
In figure 1 above,
Collision prevention girders 1, mounting base 2, buffering energy-absorbing component 3, latch plate 4, cushion collar 5, bumper post 6, anti-climbing tooth 7.
Specific implementation mode
The core of the utility model is to provide a kind of rail vehicle and its front end crash energy absorption equipment, to reduce rail vehicle
Front end crash energy absorption equipment production cost, while improving service life.
In order to make those skilled in the art more fully understand technical solution provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As shown in Figure 1, a kind of front end crash energy absorption equipment for rail vehicle that the utility model embodiment provides, including it is anti-
Hit beam 1, vehicle body bottom frame for being fixed to rail vehicle front beam mounting base 2 and be set to collision prevention girders 1 and mounting base 2 it
Between buffering energy-absorbing component 3；Buffering energy-absorbing component 3 includes latch plate 4, cushion collar 5 and bumper post compatible with cushion collar 56；
One end of latch plate 4 is fixedly connected with collision prevention girders 1, and the other end of latch plate 4 is fixedly connected with mounting base 2；One end of bumper post 6
It is fixed in mounting base 1, the other end of bumper post 6 is provided with protrusion, and raised head is embedded in the port of one end of cushion collar 5
Interior, the other end of cushion collar 5 is arranged in collision prevention girders 1, and when the extruding force between protrusion and cushion collar 5 reaches preset pressure value
When, protrusion can swell cushion collar 5.
Above-mentioned front end crash energy absorption equipment, when rail vehicle collides, the power of generation can be applied to entire front end and inhale
On energy buffer unit, after being pressurized flexible deformation can occur at first for the latch plate wherein in buffering energy-absorbing component, when the bullet of latch plate
Property deformation extent when reaching maximum, the boss of cushion collar and bumper post is hit so that cushion collar swells, i.e., latch plate with it is slow
Punching set continues to absorb energy by plastic deformation, impact force after energy absorption by end carriage effect on the car body, from
And realize buffering energy-absorbing function when rail vehicle collision.Above-mentioned apparatus overall structure is simple, and production and processing required precision is not
Height, to reduce production cost, and whole device is not related to being guaranteed with the rubber material of aging, service life.
What needs to be explained here is that when automobile crash, impact force acts on latch plate by collision prevention girders so that latch plate
It deforms.When impact force is smaller, flexible deformation will only occur for latch plate, can be restored to normal work by debugging after deformation
Make state, realizes and reuse, it is of low cost；When automobile crash and larger impact force, the flexible deformation of latch plate is not enough to
Absorb all Impact energies, latch plate will continue to occur plastic deformation to absorb Impact energy, meanwhile, cushion collar also will with it is slow
The boss for rushing column is hit, and cushion collar, which is squeezed, to swell, and absorbs more Impact energies by being plastically deformed.
In some specific embodiments, occurs the phenomenon that climbing vehicle when automobile crash in order to prevent, it refers to bumping against to climb vehicle
One vehicle of two cars the case where climbing to the top of another vehicle.Longitudinally arranged anti-climbing tooth is additionally provided in above-mentioned collision prevention girders 1
7, cushion collar 5 is through collision prevention girders 1 and is fixed on anti-climbing tooth 7.By the way that longitudinally arranged anti-climbing tooth is arranged, when automobile crash,
Anti- climbing tooth on two cars can engage alternating expression up and down, and then can limit two vehicles by interlaced anti-creep tooth engagement
Between end opposite vertical deviation occurs, and then effectively avoid the risk that vehicle is climbed when vehicle collision.
In addition the dismounting of front end crash energy absorption equipment whole device for convenience, above-mentioned mounting base 1 are to be bolted
On front beam.Of course, it should be understood that the mode that above-mentioned bolt is fixedly connected is only the excellent of the utility model embodiment
Example is elected, can be with other common fixed forms of those skilled in the art, such as the mode etc. that is welded to connect only is welded
The mode of connection mounts and dismounts inconvenience.
It is further to note that the head of the protrusion on above-mentioned bumper post 6 is typically chosen in transition with cushion collar 5 and matches
It closes, the installation for being adapted position of bumper post more convenient in this way and cushion collar, and when colliding, instantaneous force is not
The phenomenon that easy ting produce stress concentration.Of course, it should be understood that above-mentioned only the utility model embodiment is for protrusion
The preferable examples of the fit system of head and cushion collar, can also be by the way of interference fit.
